PATENT OEEIc EDWIN BENNETT, OF MILL VILLAGE, PENNSYLVANIA.

PAINT COMPOUND.

SPECIFICATION forming part of Letters Patent No. 731,660, dated June 23,1903. ll Application filed March 30, 1903. Serial No. 150,123- (Nospecimens.)

To all whom it may concern:

Be it known that I, EDWIN BENNETT, a citizen of the United States,residing at Mill Village, in' the county of Erie and State ofPennsylvania, having invented certain new and useful Improvements inPaint Compounds;

' and I do hereby declare that the following is a full, clear, and exactdescription of the same.

The present invention has for its object to provide an oil-paint thatwill be free from the oxid of iron or lead or other deleteriousingredients that would tend to cause the paint to crack, corrode, andpeel or otherwise render the same objectionable, particularly whenexposed to heat or cold or the elements.

It is the purpose of the invention to produce an oil-paint that will befree from the above objections and that will possess the necessaryelasticity to prevent it from cracking or peelmg and still retain thenecessary hardness to impart to it a wearing body and have a fine finishand gloss, such paint being equally ap- 'plicable to inside work oroutside work upon houses or other structures and also upon the roofsthereof.

In compounding my improved paint I first take one pound of gum-damar,one pound of gum-shellac, one pound of gum-tragacanth, one pound ofanimal-glue, twopounds of beeswax, two pounds of paraffin-wax, and twopounds of rosin. The above ingredients are placed in a suitablereceptacle with thirty gallons of suitable oil, preferably linseed-oil,and mixed together and dissolved by heat, which will form a homogeneousmass about the consistency of paste. This being accomplished and afterit is in a comparatively cool state,

four ounces of muriatic acid and four ounces of phosphorus may beadded,the acid cutting the compound or aiding in mixing and thephosphorus adds in giving elasticity to the paint, al-

though either of these ingredients may be dispensed with, as they arenot considered as absolutely necessary, as the gums would give the paintsufficient elasticity and render it imperviousto moisture orwater, thegums also giving the aint loss and brillianc 1 as well as elasand theparaffin-wax softens thepaint and prevents it hardening too quick, whilethe beeswax gives endurance and lasting qualities, an d the rosin willharden to a degree the paint and give it sufficient gloss for workingpurposes, so that the paint will flow evenly and present a-smooth andglossy appearance. After the several ingredients are mixed with the oiland dissolved by heat and the acid and phosphorus added, as hereinbeforedescribed, a sufficient quantity of powdered shell-rock is added to makefifty gallons of paint at the required consistency for use, and anysuitable coloringmatter may be added to give the paint the requiredcolor or tint.

' Theshell-rock, comprising one of the essential features of the paintcompound, is peculiarly adapted as a pigment, and to describe it inbrief this rock is found in layers of difierent strata some distancebelow the surface of the earth, and between the rock and earth is alayer of roshell ocher. Veins of water run out of the rock, which keepit moist and soft and when found is in the consistency of earth, butwhen exposed to the air it becomes hard, similar to stone, and in itsmoist state it pulverizes easily and dries quickly. The shellrock isconsidered of material importance in the preparation of this paintcompound, as it not only takes the place of oxid of iron or lead orother like injurious ingredients usually employed in the manufacture ofpaint,.but

. the shell-rock will greatly add to the wearing qualities thereof andrender the paint absolutely impervious to moisture or the elements andcan be used in any climate with equal success, the shell-rock renderingthe paint comparatively indestructible, and in this particular it isinvaluable as a paint for roofs or for covering a metal surface.

Driers may be added to the paint as required; but this is left optionalwith the userof the paint, and I wish it to be understood that theproportions named may be variously modified or changed in compoundingthe paint, and I do not desire to confine the invention to any rock, anda suitable oil, substantially in the particular amount of ingredientsused. proportions named. :0

Having now fully described my invention, In testimony whereof I affix mysignature what I claim as new, and desire to secure by in presence oftwo witnesses. 5 Letters Patent, is I EDWIN BENNETT.

A paint compound consisting of gum-dalnar, gum-shellac, gum-tragacanth,animal-glue, beeswax, paraffin-wax, rosin, pulverized shell- WVitnesses:I F. H. HUBBARD,
